A warning sign
Roundabout ahead
A red triangle with three curved arrows warns of a roundabout ahead - get ready to give way to traffic from your right.
01
What it means
A roundabout is coming up. Slow down, pick your lane and exit early, and give way to traffic already on the roundabout coming from your immediate right (Highway Code Rule 185), unless signs or lights say otherwise.
02
Where you'll see it
On the approach to roundabouts, especially larger or faster ones where you need time to position.
03
On your driving test
Roundabouts are where lane discipline and observation get marked. Choose the correct lane early, signal correctly, and only go when it's safe.

Quick answers
Who has priority at a roundabout?
Give way to traffic coming from your immediate right, unless road markings or traffic lights say otherwise (Rule 185).
How is it different from a mini-roundabout?
Same give-way rule, but a mini-roundabout has a painted central circle you must drive round; a normal roundabout has a raised island. Our full guide to every roundabout type is at /knowledge-hub/roundabouts.
